[Implantation of mitral valve prosthesis with continuos suture]

The results obtained in 20 patients with the use of continue suture technic for prosthetic implantation of the mitral valve were compared to those observed in other 20 patients in which the prothesis were implanted with isolated suture technic. With the first one the aortic clamp time was reduced in average about 50 minutes; the extracorporeal circulation time also diminished in the same proportion. One patient died in each group, meaning a 5% of hospital mortality. The going after time in the first group was 2.5 years and in none was found prosthetic dysfunction or perivalvular lickage. We conclude that prosthetic implantation technic for mitral valve with continue suture, offers the following advantages: a) Important reduction of the transoperative myocardial ischemia. b) Reduction also, of the hole estracorporeal circulation time. c) Minor possibilities of periprosthetic lickage. d) Minor risk of valvular thrombosis in the suture line.
